The tooth has several layers (enamel, dentin and vital part). The outer part of the tooth consists of two layers: first, the outer layer, the enamel, and the dentin. Each of these layers has its own natural colour.

In general, the color of the teeth becomes darker with age.

Normal wear and tear on the enamel, which is generally lighter or transparent, reveals the dentin, which is more yellowish.

The change in the colour of the teeth usually affects all teeth, but can affect a single tooth under special conditions.

• Time;
• Normal wear and tear of the enamel;
• Repeated consumption of pigmented drinks (coffee, tea, red wine or brown sodas);
• Smoking, poor dental hygiene;
• Taking certain medications (especially tetracycline at an early age or in pregnant women for their infants).

When the causes of the stains are well controlled, the patient may decide, for aesthetic reasons, to clarify his teeth. It will then be possible to consult your dentist to choose the best solution to restore whiteness to your teeth. Possible options are: chair whitening treatment in the dental office or at home.

• Decrease in the consumption of pigmented foods;
• Quitting smoking;
• The use of appropriate hygiene products;
• Healthy dental hygiene habits.
